About this network

A payment processor's single /24, dual-homed and registered in its own name.

What it's used for

• Corporate and payments connectivity. 256 addresses in a single /24 with two observed BGP neighbours and no IPv6 announced.

Notable

• The one block, 198.252.230.0/24, is netname NAB-NET1, registered to North American Bancard, LLC.
• Handle, holder and netname all reduce the same company name three different ways: NABANCARD, the full legal name, and NAB.
• First seen in routing data in December 2012.
• Two neighbours rather than one.

Interesting

• Merchant acquiring is the business of standing between a shop's card terminal and the card networks. The money moves in batches and the authorisations move in milliseconds, and the second of those is why a /24 this small has two upstreams: a declined transaction because a link was down is a lost sale in somebody's store, immediately and visibly.
• 2012 is late for a first appearance in routing data, and it fits a company that ran on its provider's addresses until the compliance requirements of card processing made owning the space and the routing worth the paperwork.
